.ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 352,841, dated November 16, 1886. Application filed December 7, 1885. Serial No. 184,978. (No model.) Patented in England January 2-1, 1885, No. 1,040.

1885,) of which the following is a specifi'cation.

Heretofore in the specification and drawings of my British Patent No. 5,046 of 1880 I described an adjustable anti-friction roller bear- 1 5 ing in a form which contained substantially a rectangular cylindrical recess in a hub or box,

and a substantially rectangularbylindrical recess in an axle or between sleeves thereon, a cap threaded in the. hub or box, a sleeve 2o threaded on the axle, and two rows of rollerdisks having axes inclined to "the axle and alternately placed in the recesses for each side of the wheel, and I have set forth this form of bearing in my application for Letters Patent of the United States filed August 9, 1886, and

my present invention is in the line of improve' ments on the construction there shown, with a View to reducingthe cost of making such bearings, and rendering them" more simple,

3c certain and effective; and it consists in combining a single row of such prolate spheroidal or similarly-for1ned disks with curved bearingsurfaces in box and collar, concaved or grooved toward the bearing-surfaces of the rollers at 3 5 each side of the bearing, and a single advancing ring or collar for adjustment, and with "suitable modified connections in its embodiment in a bearing. 4

I will now describe my present improve- 4o ments.

I fit in the annular space of the bearings small disks of steel, or like hard metal, with rounded or formed edges arranged to work on or in curved or rounded grooves or surfaces,

5 the diameter of the rollers being such with re-. spect to the annular space between the shaft spindle or pivot and the bearing box or case that when dropped into the box or case they will necessarily take an inclined position. As the disks become worn their diameter will be reduced, and by screwing up the cap or cover the curved or rounded grooves or surfaces formed onthe hub or bearing box or case and the shaft spindle or pivot will be forced against the angular rollers, bringing them in a more upright position, and so adjusting the bearing. In aback-wheel bearing, the disks are arranged in a single row on each si(le,'and run in curved inclined grooves formed in the hub, and in adjustable curved grooves in the spindle or shaft, such adjustable grooves or surfaces being set up by lock-nut or otherwise. vBy this method of constructing roller-bearings I provide a much simpler adjustment than in my former patent. The wearing-surfaces are increased, as the rollers canlbe madeto fit the grooves, and altering the angle of their plane of rotation does not make any appreciable difference to their working-surfaces.

The accompanying two sheets of drawings are illustrative of details of my invention as applied to various parts of velocipedes.

Figure 1 is a vertical section of a back-wheel or hub bearing; Fig. 2, a vertical section of a pedal-bearing; Fig. 3, a front elevation of a cage which may be used with my rollers; Fig.

4, side elevation of same; Fig. 5, enlarged vertical section of part of a hub, showing a modification of my invention. Figs. 6 and 7 are vertical sections of modifications.

A A are theforks supporting the spindle B, which screws into one fork, A, and, passing through the other, is secured by nut or other-' wise.

C is the hubof the wheel,formed with curved 85 or roundedsurfaces D D E E, as shown.

The spindleB is-screwed at F F to fit screwed collarsG G, in which rounded or curved surfaces H H are formed. These collars G G may be set up by inserting a pin in holes I I I I, provided in the same, or in other suitable manner, as will be well understood. Locknuts J J secure same in position. The angular rollers K K K K are formed with rounded or curved surfaces, and are placed so that in a section taken through the bearing each opposite pair of rollers converges in respect of the axes of the same, as shown. If it is desired that the rollers should not touch each other, each roller is inserted in a hole in a cage formed of hardened steel or like suitable metal, as shown in Figs. 3 and 4, and I do not claim the use of a cage to contain or separate rollers or balls generally, as such is well known.

In regard to the pedal-bearing shown in Fig. 2, A A are the pcdalplates; D D the rounded surfaces thereon; B, the pin; 6*, one screwed collar fast to the pin B; J, the nut locking G J the nut securing the pedal to the crank; H H", the rounded surfaces formed on collars G G K K K K, the rollers.

An obvious modification of my invention will be seen in Fig. 5, which consists in making the rollers of a V-section to run on the rounded surfaces formed to suit. G is the hub; B", the spindle; D D", the rounded surfaces, formed as shown in the drawings, so as to fit each bevel of the V-roller; F", the screwed part of spindle 13"; J lock-nut; G the collar with corresponding surfaces, H H; K K the said rollers.

On screwing up the collars on any of these figures the distance between the curved surfaces on the spindle and those on the hubbearing boxor case is reduced, and so the rollers are tilted or moved, so as to take a less inclined position, and so adjust themselves to or compensate for the wear or slackness of the bearing,

Fig. 6, Sheet 2, is a vertical section of a bicycle-fork hearing. In this L is the case, formed with rounded surfaces M M M M therein. N N are two collars, the one formed with a screw portion, 0, for the other portion,

, being the rounded surfaces thereon.

N, to screw on. N is keyed, shrunk, or otherwise fastened to the spindle P, carrying the hubs. The rounded surfaces Q Q Q, Q are formed on these collars N N, or they can be formed to fit rollers, as in Fig. 5. R R R R are the rollers in two rows. The adjustment is by screwing up collar N. I might adapt a single row of my rollers for this form of hearing in place of a double, if desired.

Fig. 7 is a vertical section of a bearing for asociable or other tricycle, in which I have shown two rows of rollers running in the same angular plane. S is, one collar fixed to the through-axle T of the balance-gear, U U U U V is the other collar or case, screwing into the covering or supporting tube V, and stepped to get the rollers into position; X X X X, surfaces on this collar; Y Y Y Y, the rollers; Z, locknut. Settingnp the collar V alters the inclination of the rollers Y. More than two rows of rollers may be used, if desired, for a heavier bearing of this description. The alternative form of rollers and surfaces might also be used for bearing.

I have not shown other drawings illustrat ing the application of my invention to other varieties of carriages or mechanism other than Velocipedcs; but such application will be at once perceived on reference to the aforesaid drawings, which elucidate the principle of my invention.

I am aware that bearings of the general class herein described have been constructed with plain cylindrical rollers, and roundended rollers, and conical-ended rollers, and spherical rollers, wherein the axes of revolution of the rollers were parallel with the axis of the shaft about which they were placed, and that in some of these hearings movable caps or cones have been used as means of adjustment, and I do not claim these things or their combi: nation in a bearing; nor do I claim one or more series of prolate spheroidalorsimilar]yshaped rollers having inclined axes, nor the combination of bearing-surfaces in box and axle sub: stantially perpendicular to and parallel with the axis of the shaft, one or more of said perpendicular surfaces being adjustable, and one or more series of such inclined rollers in a bearing of this class, because I have claimed these,

among other things, in my said application filed August 9, 188 6.

I claim as new and of my invention- The combination, in an antifriction bear ing, ofcurved or rounded bearing-surfaces on or carried by the shaft or axle, and similar curved or rounded bearingsurt'aces in or car-, ried by the hub or box, the radii of the curves ofsaid bearingsurfaces being inclined to the axis of the shaft, a series of roller-disks having their axes inclined to the axis of the shalt and rounded or formed upon their peripheries to bear or revolve upon the said curved or rounded bearing-surfaces at either side of the bearing, a means, substantially as described, for changing and securing one or more of said curved or rounded bearing-surfaces laterallyv in position, so as to change the inclination of the disks and adjust the bearing, essentially as set forth.
